Thin quarter

[bk]

Does anyone know anything about this coin. It's a 1976-D Washington quarter found in circulation. Apparently it was struck on dime stock. A couple of short articles in "Coin World" appeared shortly after this coin was first discovered. I have not heard anything since.
Any idea as to value?

Oops, should be a 1970-D quarter. Not 1976.

Supply and demand determine price. Since as many as several thousand of these error coins were struck the supply is much higher than the stray coin typically struck on the wrong planchet.

I found this AU example for sale for $40. http://www.fredweinberg.com/inventory/item.asp?ID=3231

Thanks Klaatu,
I knew I would hear from you on this one. I got this in change in the early 70's and suspected something was "not right" with it. At least there is some documentation on it.
It only cost me a quarter.

That's a great find. I would gladly give 25? for one.

I have looked for these in change but came up empty, are they really thinner, or barely noticable? I wonder what the chances of finding one in quarter rolls is?

Jake,
When I found this coin, I knew something wasn't quite right about it. It was only the thickness of a dime, a very unusual (weak) strike, and sounds like a poker chip when dropped on a table. The coin was new when I got it, but looks like it was in circulation for many years.

The reason the coin is a weak strike is because it was struck on a dime planchet and the dies are spaced for a thicker quarter planchet. The dies simply stopped before a strong impression could be made because the planchet was so thin.

Hi,
The coin needs to be weighed to see if it is an error or not. It is possible it was struck on a dime planchet but weighing it is the only way to determine that.

A quarter should weigh 5.67 grams...a dime planchet would weigh 2.27 grams. Anything in the middle is just wear.

A friendly pharmacist might weigh it for you.

Good Luck,
Bill

The problem with that scenario is that if the quarter was struck on a dime planchet, it would fit neither the quarter weight, since the metal was thinner, nor the dime weight, since the quarter is struck larger than a dime. This will invariably fall in between those two weights. A better test would be to compare the thickness of the thin quarter with an equally worn dime from the same year or thereabouts.

Just a random thought.
If the planchet was both dime thickness and dime-sized diameter, it would way 2.27 g. But if it was dime thickness but quarter sized diameter, it would be somewhere between 2.27 and 5.67.
